Low- and middle-income countries such as Kenya are paying more
for medicines than rich States, according to a new report from the
Centre for Global Development.
The report published
this week indicates that patients in low- and middle-income countries
pay as much as 20 to 30 times above the minimum international reference
price for basic generic medicines like omeprazole, used to treat
heartburn, or paracetamol, a common pain reliever.
The
biggest contributor to these price variations, the reports shows, is the
fact that those countries tend to buy the most expensive drugs as
opposed to opting for the cheaper unbranded generics.
“In
the poorest countries, branded generics — which command a price premium
— make up about two-thirds of the market by volume and value. Unbranded
generics, usually the least expensive option, are a tiny sliver, only
five percent of the market by volume and three percent by value.
In
contrast, in the United States (US) and the United Kingdom, unbranded
quality-assured generics account for 85 percent of the pharmaceutical
market by volume, but only about a third by cost,” shows the report.
Medicines often have more than one name — a generic name given to the active ingredient and a brand name.
The
brand name is chosen by the manufacturer to help with marketing. For
example, Lipitor is the brand name given by Pfizer to the generic
medicine atorvastatin, which is used to reduce the risk of heart attack.
Medicines also contain inactive ingredients, which are used to
formulate the active ingredient into a tablet, liquid or cream, and
these can vary.
This is why medicines containing the
same active ingredient, but made by different manufacturers, may look
different. These differences are rarely significant, which is why
generic and branded medicines are almost always interchangeable.
The report states that rich countries are able to rely on the
unbranded generic drugs because their governments have well-functioning
regulatory systems that assure their citizens that the generic medicines
meet the quality standards.
By contrast, patients in
low- and middle-income counties often cannot rely on regulatory systems
to keep poor-quality drugs off the shelves and as a result, use of and
expenditure on cheap unbranded generics is relatively low.
And
because of the quality query it is difficult for the unbranded generics
to compete with the branded variety, leaving patients with little
choice but to dig deeper into their pockets for the expensive drugs.
Another
contributor to the price variation, the report shows, is the barriers
to entry of new drugs which it says prevent new suppliers from entering
the market and may allow existing manufacturers to keep prices above
market-clearing levels.
“Studies suggest that limited country-level competition may directly affect the prices paid by consumers and public procurers.
In
the US, a 2005 study showed that a first generic competitor is priced
at a modest discount from the originator brand, but additional entrants
push down average generic pricing substantially — from 94 percent of the
originator price for the first generic entrant to 52 percent after the
second entrant, 33 percent after the fifth entrant, and as low as six
percent once there are 19 generic products competing in the
marketplace,” the report states.
The report comes at a
time when insurers in Kenya estimate that patients are paying at least
50 percent more for their medications due to over-prescription of
branded drugs.
In a recent interview, Jubilee Holdings chairman Nizar Juma said that Kenyans still prefer branded drugs over the generics.
“In
Kenya, we are using more brands than generics yet economies like the US
use 80 percent generics despite being richer than us. Doctors, patients
and hospitals are united in this,” said Mr Juma.
The debate has sparked a row between insurers and doctors and
insures who believed that the cost of medication could be cut down
extensively with introduction of more unbranded drugs into the market.
Madison
General Insurance, this year directed doctors to only prescribe generic
medicines for its customers, kicking up a storm after medics vowed to
defy the order.
Doctors argued that although generic
drugs have the same active ingredient as branded drugs, they are
composed differently. This means that they may have different
bioavailability from either the branded drugs or, indeed, other generic
drugs of the same class.
Typically, this would not
affect the patient in terms of efficacy and safety, but in drugs with a
narrow therapeutic index, this could potentially lead to adverse
effects, the doctors said.
The report recommends
greater global co-operation and reforming World Health Organisation
policy as well as policy in targeted countries to improve procurement
practices.
It states that low- to middle-income
countries "have little ability to negotiate prices down and quality
assure products" and there are lots of markups, often due to taxes and
corruption
